Re: Smpeg MMX asm compilation (problem)

[Matt <moc dot pophot at hotpop dot com>]

Alright, I've managed to get both .S files to compile- however when I 
try to link them with a program using:
extern "C" {
extern unsigned int cpu_flags(void);
extern void IDCT_mmx(DCTBLOCK data);
}

The linker tool comes up with
./.libs/libsmpeg.a(parseblock.o): In function `Z8InitIDCTv':
e:/programming/smpeg/video/parseblock.cpp:117: undefined reference to 
`cpu_flags()'
./.libs/libsmpeg.a(parseblock.o): In function 
`Z15ParseReconBlockiP10vid_stream':
e:/programming/smpeg/video/parseblock.cpp:583: undefined reference to 
`IDCT_mmx(short*)'

They *are* getting assembled&linked- Why is this??
Here's the code for the mmxflags_asm.S, which should be enough for you 
folk to figure it out:
"
.text
    .align 2
.globl cpu_flags
    .def    cpu_flags;    .scl   2;      .type 32;    .endef
cpu_flags:
        pushfl
        popl %eax

        movl %eax,%edx

        xorl $0x040000,%eax
        pushl %eax

        popfl
        pushfl

        popl %eax
        xorl %ecx,%eax
        jz cpu_flags.L1   # Processor is 386

        pushl %ecx
        popfl

        movl %ecx,%eax
        xorl $0x200000,%eax

        pushl %eax
        popfl
        pushfl

        popl %eax
        xorl %ecx,%eax
        je cpu_flags.L1

        pushl %ebx

        movl $1,%eax
        cpuid
        movl %edx,%eax

        popl %ecx

cpu_flags.L1:
        ret
